carry out clamping bolt, the problem how bolt is tightened becomes a difficult problem, due to the restriction of punching spatial position, inclined-plane and structure, two both sides, tooth section inclined-planes can only respectively process a hole, only connect large diameter ring gear by two Bolt Connection, from strength and stiffness, all there is huge hidden danger, and this inclined-plane hole knockout has destroyed the integrity of gear ring both side surface, cause stress to concentrate, and there will be and have a lot of metal acute angles, and sharp, easily cause that operator scratch etc. and cause security incident, the connection precision of two tooth sections of this technology guarantees by hole, hence one can see that cannot guarantee that two tooth section inclined-planes combine the assembly precision while connection at all, bolt plays anastomosis, positioning action and limited.Gear is as precision drive part, very responsive to error, when the single hop ring gear that separates in addition axially and Radial Combinations connects, be difficult to assurance left-right rotary to two gear ring teeth directional centerings good, whole gear ring each tooth of a week all exists left-right rotary to larger teeth directional error of centralization, and radial direction and circumferencial direction cannot accurately be located, will produce so larger axial force, affect transmission stability etc., thereby lose the part advantage of herringbone tooth.
